How is it a ballpoint pen which did not work previously, miraculously starts working again when you make a few scratches with it on paper? What’s the mechanism behind it?
In: Engineering
I am not an expert, but it’s a tiny ball that rolls in every direction, picking up ink from the stem and leaving it on the paper. At times, it feels like the ball gets stuck for some reason, and and the hard pressure of scribbling in multiple directions on paper seems to “unstick” it.
